Reaction of Sn44- in liquid ammonia: The formation of Rb6[([small eta]2-Sn4)Zn([small eta]3-Sn4)] [round bullet, filled] 5NH3

18-09-2013 | Franziska Fendt; Carina Koch; Stefanie Gaertner; Nikolaus Korber, Dalton Transactions, 2013

The reaction of Rb4Sn4 with ZnPh2 in liquid ammonia in the presence of [2.2.2]-cryptand yielded crystals of Rb6[(η2-Sn4)Zn(η3-Sn4)] • 5NH3, which could be characterized by single crystal X-ray diffraction. This is the first example of a successful solution reaction of the highly charged ...

Efficient functionalization of multi‐walled carbon nanotubes with p‐aminophenol and their application in the fabrication of poly(amide‐imide)‐matrix composites

12-09-2013 | Shadpour Mallakpour, Amin Zadehnazari, Polymer International, 2013

Abstract The ultrasonic‐assisted preparation and characterization of poly(amide‐imide) (PAI) composites containing functionalized multi‐walled carbon nanotubes (MWCNTs) are reported. To improve the dispersion and compatibility with the polymer matrix, the MWCNTs were surface‐modified with ...

Topochemical control of the photodimerization of aromatic compounds by γ-cyclodextrin thioethers in aqueous solution

12-09-2013 | Hai Ming Wang and Gerhard Wenz, Beilstein Journal of Organic Chemistry, 2013

Abstract The formation of soluble 1:2 complexes within hydrophilic γ-cyclodextrin (γ-CD) thioethers allows to perform photodimerizations of aromatic guests under controlled, homogenous reaction conditions. The quantum yields for unsubstituted anthracene, acenaphthylene, and coumarin complexed ...

Cooperative Assembly of Discrete Stacked Aggregates Driven by Supramolecular Host–Guest Complexation

12-09-2013 | Nuno Basílio; Ángel Piñeiro; José P. Da Silva; Luis García-Río, The Journal of Organic Chemistry, 2013

p-Sulfonatocalix[4]arene (SC4) interacts with the aromatic dye crystal violet (CV) to form complexes with stoichiometries ranging from SC4:CV = 1:1 up to 1:5 both in solution and in the gas phase. While the 1:1 complex is of the inclusion type, as frequently observed for other guests, in the ...

Hydrolysis of mixed Ni2+-Fe3+ and Mg2+-Fe3+ solutions and mechanism of formation of MII-FeIII layered double hydroxides

11-09-2013 | Brian Grégoire; Christian Ruby; Cedric Carteret, Dalton Transactions, 2013

The hydrolytic behavior of mixed metallic solutions containing Ni2+-Fe3+ and Mg2+-Fe3+ has been studied with respect to the relative proportion of the divalent and trivalent cations in solution as well as the quantity of NaOH added. The combination of X-ray diffraction and vibrational ...

Theoretical Investigations into the Nucleation of Silica Growth in Basic Solution Part II – Derivation and Benchmarking of a First Principles Kinetic Model of Solution Chemistry

11-09-2013 | Grant Jason McIntosh, Physical Chemistry Chemical Physics, 2013

A kinetic model of silicate oligomerization in water, up to and including tetramer formation, has been compiled exclusively from rate constants derived from transition state theory based on either quantum chemical data (derived under a hybrid solvation framework) for all bond breaking/forming ...

Bio-functionalization of multi-walled carbon nanotubes

11-09-2013 | Anindya Majumder; Maryam Khazaee; Jörg Opitz; Eckhard Beyer; Larysa Baraban; Gianaurelio Cuniberti, Physical Chemistry Chemical Physics, 2013

Here we present a hybrid approach to functionalize multi-walled carbon nanotubes in aqueous solution, exploring a non-covalent binding strategy. We focus on formation of hybrid complexes consisting of carbon nanotubes decorated by single stranded DNA, non-covalently attached using surfactants as ...
